Two Odorant-Binding Proteins Involved in the Recognition of Sex Pheromones in Spodoptera litura Larvae.

Journal of Agricultural and Food Chemistry, 2022
Usually, the recognition of sex pheromone signals is restricted to adult moths. Here, our behavioral assay showed that fourth-instar Spodoptera litura larvae are attracted to cabbage laced with minor sex pheromones Z9,E12-tetradecadienyl acetate (Z9,E12 ...

Genome-Wide Analysis of Odorant-Binding Proteins in Papilio xuthus with Focus on the Perception of Two PxutGOBPs to Host Odorants and Insecticides.

Journal of Agricultural and Food Chemistry, 2022
In this study, we annotated 49 odorant-binding proteins (OBPs) in Papilio xuthus, with four novel genes and seven improved sequences. Expression profiles identified numerous OBPs in antennae or reproductive tissues.

Coordinative mediation of the response to alarm pheromones by three odorant binding proteins in the green peach aphid Myzus persicae.

Insect Biochemistry and Molecular Biology, 2021
Odorant binding proteins (OBPs) play an essential role for insect chemosensation in insect peripheral nervous systems of antennae. Each antennal sensilla contains more than one OBP at high concentrations but the interactions and cooperation between co ...

Ligand-binding specificities of four odorant-binding proteins in Conogethes punctiferalis.

Archives of Insect Biochemistry and Physiology, 2022
Odorant-binding proteins (OBPs) play essential roles in lepidopteran insects' perception of host volatiles by binding and transporting hydrophobic ligands.

Mammalian odorant binding proteins

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 2000
Odorant binding proteins (OBPs) pertain to one of the most abundant classes of proteins found in the olfactory apparatus. OBPs are a sub-class of lipocalins, defined by their property of reversibly binding volatile chemicals, that we call 'odorants'. Numerous sequences of OBPs are now available, derived from protein sequencing from nasal mucus material,

Odorant-binding proteins in insects

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995
This paper reviews the characteristics of pheromone and odorant-binding proteins (OBP) in insects, with particular reference to Lepidoptera. They are small (15 kDa) soluble proteins, very concentrated in the lymph of chemosensory sensilla and belonging to two major classes, pheromone-binding proteins (PBP) and general odorant-binding proteins.

BarH1 regulates odorant-binding proteins expression and olfactory perception of Monochamus alternatus Hope.

Insect Biochemistry and Molecular Biology, 2021
Insect odorant-binding proteins (OBPs) are a class of small soluble proteins that can be found in various tissues wherein binding and transport of small molecules are required.

Deswapping bovine odorant binding protein

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2008
The X-ray structure of bovine Odorant Binding Protein (bOBP) revealed its association as a domain swapped dimer. bOBP, devoid of any cysteines, contrasts with other mammalian OBPs, which are monomeric and possess at least one disulfide bridge. We have produced a mutant of bOBP in which a glycine residue was inserted after position 121.

Odorant-Binding Proteins

Critical Reviews in Biochemistry and Molecular Biology, 1994
Odorant-binding proteins (OBPs) are low-molecular-weight soluble proteins highly concentrated in the nasal mucus of vertebrates and in the sensillar lymph of insects. Their affinity toward odors and pheromones suggests a role in olfactory perception, but their physiological function has not been clearly defined.

Functional characterization of four antenna-enriched odorant binding proteins in Rhaphuma horsfieldi reveals the importance of RhorOBP1 in odorant recognition and insecticide resistance.

Pesticide Biochemistry and Physiology
The cerambycid beetles are key players for the sustenance of biodiversity in the forest ecosystem, but in most cases are well known due to their harmfulness to agricultural and forest plants.
